The Outside
1) Inputs: The inputs of MEGA BASS use a balanced input circuit to help minimize feed back. They are also
designed to handle very high signal voltage up to 15 volts.
2) Outputs: These RCA connectors should be connected to the next component after MEGA BASS, such as a
crossover, equalizer or amplifier. Just remember that MEGA BASS should be in line before a crossover.
3) Dash Input Control: This allows you to connect MEGA BASS to the remote control knob. You can mount the
knob anywhere you want, although somewhere in the font of the vehicle is most common. (Remote Must Be Connected
For The Unit Operate Correctly)
4) Power Connection: This connector allows you to connect the Ground and Remote TURN-ON signals to
MEGA BASS. Connect all of the wires to their appropriate locations in a well lit area and then plug it into MEGA BASS
where ever you decided to mount it in your vehicle.
5) Bass Controls: These 2 knobs control the bass functions fo MEGA BASS.
The SWEEP knob allows you to pick the center frequency that you want MEGA BASS's restoration circuit to maximize.
The WIDE knob adjust how wide of a frequency range MEGA BASS will effect.
6) Power: When you have connected all of your wires correctly the POWER light should illuminate. If it does not
then you need to check your wires.

The Inside
1) Input Grounding: For most systems you can leave this jumper set in the BALANCED position. In some
systems, the source unit may look for a ground through the RCA connectors. In that event, you should go ahead and
change the jumpers to the UNBALANCED position.
2) Ground Isolation Jumpers: Occasionally alternator whine may appear in a system because the source unit
and amplifier may use different grounding. To help in this situation, we have provided alternative grounding connections.
Make sure your system is turned OFF bore you move these jumpers.
3) Bass Output Control Jumpers: Not all systems are designed the same, some systems are designed strictly
for SPL while other are for average use. MEGA BASS's maximizer circuit can either increase or decrease the signal
voltage of the bass restoration circuit. Depending upon your system, you may want to change these jumpers to a higher or
lower setting to maximize your bass output and protect your speakers. In most systems the factory setting will suit you
fine. We recommend that you try the factory setting before any other.
